Sorry, but nobody deems JWs as "Protestants" -- including JWs themselves.
Mormons & JWs are similar in this way in that NEITHER deem themselves to be Protestant...
They both think they're the ONLY TRUE religious "game" in town...
Documentation for Lds on that: D&C 1:30...and I can get it for you on JWs, if you like.
That's actually what's kind of strange about those who defend Mormonism.
They somehow think that Mormonism's declaration that EVERY other religious entity is false and dead is suppose to get a 100% "lay down" effect...as if nobody's going to respond to that kind of worldwide slander.
The same is true re: JWs.
I confess I don’t know much about JWs, other than that the ones I’ve personally known have always insisted they are Christians.
